These are basically the same cut, except the longer hair has extensions.
The back and crown are disconected from the front. Heavy texturized layers in the back and crown, you can use a razor with long strokes or deep point cutting with shears. The front has more length and also has some texturizing.
These are very simple, fun, and quick cuts because there is no precision involved. You "feel" the cut, sort of like a jam session for musicians where they don't read notes but every one plays what inspires them.
